Product Information

Agency Power has developed one of the best sounding and performing exhaust systems for the 2011 STi Sedan. The new exhaust features an all T304 stainless steel piping in 3inch diameter from the catback. The piping is all hand polished featuring robotic TIG welding. The midpipe includes a resonator to assist in keeping that traditional boxxer engine sound with an exotic race tone touch that does not drone in the cabin. The ½ inch thick flanges offer a secure fit along with the factory placement exhaust hangers. The catback exhaust uses a high flow Y-Pipe to efficiently direct exhaust to the dual exhaust canisters. The Y-pipe features a merged collector and 3 inch piping on each extension to give your exhaust a combined 5 inches of exhaust flow. The straight through mufflers are designed to optimize horsepower with very little restriction. The catback exhaust features quad 3.5 inch tips with the Agency Power logo. As tested on a Mustang all wheel drive dyno, the Agency Power catback exhaust made an impressive 17 all wheel horsepower and 28ft/lbs of torque. The exhausts are available for 2011-2015 STi WRX Sedans.

TEXT_OF_5_STARS by Keith Gomes
"Spoke via Chat with a gentleman named James McKibben. I too am in customer service so understand the challenges and importance of customer relations. I would like to give this agent the absolute best rating possible. He was knowledgeable, patient, helpful and courteous. He helped me for what must be the longest chat ever, over 2 hours and was patient the entire time, researching options and providing me with as much information as possible to make my decisions. Do what you can to keep this individual with your company, he is obviously extremely dedicated, incredibly knowledgeable and loves what he does. I will be back for more later in large part due to him."

"I bought an Exedy stage 1 clutch with Exedy flywheel. I had it on a previous honda I had, Now I have it on my 89 civic wagon its a great clutch I'm still breaking it in and what else can I say I had it in two cars already."

"I purchased the Akrapovic Evolution Exhaust and AMS downpipes for my Nissan GT-R through Josh at VividRacing. He provided great customer service and items were shipped and delivered in 3 business days. Exceptional turn around time. I will definitely do business with them again in the future."

"I bought a Renntech Carbon Fiber Front Strut Brace for my Mercedes Benz C63 AMG from Vividracing recently. After a month of Vividracing fighting with renntech the undamaged part was finally received. Long story short, the original part was sent to me damaged and I immediately notified Vividracing who had to fight with Renntech (and even have their owner call Renntech directly tio get it resolved!) Renntech was claiming the part was damaged during installation. While I realize there are people out there like that, this is certainly not the case with me. The part was literally opened by me as soon as I got home from my office to find it dfamaged, I never even full yunwrapped it but yet Renntech claimed I must have damaged it installing it. They held their ground and did not care about my business to any extent as they ended up finally replacing the part but making Vividracing pay for the shipping. The Renntech part is of very high quality, but unfortunately for Renntech their service doesnt match their quality, atleast in this case. I highly recommend Vividracing and would like to personally thank Adam, Emily and the owner over at Vividracing for really pushing this and doing the right thing. I have already decided to install the part and get photos posted for them. They have earned a loyal customer! Thanks again Vivid!"

"The brake kit was simple to install and fit perfectly. The rear heat shield had to be trimmed to clear the rotor. I had to fabricate small heat shields to protect the upper and lower ball joints since the car sees a lot of track time (10+ track days/year). The front heat shields did not need modified in any way. The brake lines were a snap to install and bleeding the brakes was straightforward. I have yet to get the car on the track with the new brakes. I can say that on the street the brakes are very quiet and stop well. My car is stiffly sprung, so front dive is minimal. The difference in brake bias is noticeable, with the rear pulling down much more than with the stock Brembos. The pedal is more firm; however, it requires more pressure than the stock brakes. I have driven in the rain and warm temperatures but not in the cold. The brakes are just as quiet as the stock set up so far. The calipers clear Enkei 18x9.5 +15 perfectly and look great since they are somewhat stealth given the metalic finish."
